It includes a positioning plate, a tensioning mechanism, and a bottom plate, a guide seat, a positioning base, a locking block, a cylindrical pin, an elastic reset device, and an upper die. The positioning base is sleeved on the upper portion of the guide seat. The upper end of the guide seat is provided with an outer conical portion. A second circular hole is provided in the positioning base at a corresponding position. The outer wall of the upper end of the second circular hole is provided with N square holes evenly distributed around the circumference.

The elastic reset device is located between the positioning base and the guide seat.

[0003] The upper die is driven downward by the press, and the upper die drives the workpiece and the positioning base downward together, driving multiple locking blocks to move downward and outward at the same time, tensioning the corresponding magnetic tiles.

[0004] This mechanism is a semi-automatic magnetic shoe tensioning mechanism with low efficiency. It is prone to misalignment and missing components. If such a situation occurs, manual processing time is long. There is no detection device. If the misalignment and missing components are not discovered, it will have a significant impact on the subsequent process. It also causes significant damage to the mechanism and is not conducive to subsequent maintenance and repair. Summary of the Invention

[0005] To address the problems presented in the prior art, the present invention provides a fully automatic magnetic shoe tensioning mechanism. By optimizing the structural design, precisely calculating the strength and lifespan of each component, and adding a detection device, this mechanism improves work efficiency, reduces mechanical failure rates, minimizes mis-installation and missed installation, and facilitates subsequent maintenance.

[0006] The technical solution adopted in the present invention is:

[0009] The rotating guide plate is provided with N radial strip grooves evenly spaced along the circumference, which are used for the magnetic tile leaf spring to pass through and guide the movement. A rotatable displacement turntable is provided between the rotating guide plate and the mounting base. The displacement turntable is provided with N spiral waist-shaped grooves evenly spaced along the circumference, which are used for the magnetic tile leaf spring to pass through and guide the rotation. A radial extension arm is fixed to one side of the displacement turntable, and the radial extension arm is hinged to the magnetic tile support mechanism.

[0010] The rotating guide plate is positioned and installed through the turntable positioning pin mounting base through the surrounding edge. The turntable positioning pin between the rotating guide plate and the mounting base is sheathed with a support shaft sleeve. The upper and lower ends of the support shaft sleeve are respectively connected to the bottom surface of the rotating guide plate and the top surface of the mounting base for supporting and installing the rotating guide plate.

[0011] In the groove, the magnetic tile leaf spring is arranged in the middle, and magnets for magnetically adsorbing the magnetic tiles of the rotor assembly are provided on both sides of the magnetic tile leaf spring.

[0012] The magnetic tile leaf spring is L-shaped, one end of the L-shaped magnetic tile leaf spring is horizontally arranged as the bottom end, and one end of the L-shaped magnetic tile leaf spring is vertically arranged as the top end. The top end of the magnetic tile leaf spring can be horizontally movably embedded in the groove position of the magnetic tile support hand, and the top end of the magnetic tile leaf spring is provided with an elastic spring structure for contacting the magnetic tile of the rotor assembly on the radially outward side. The bottom end of the magnetic tile leaf spring can be horizontally movably embedded in the radial strip groove of the rotating guide plate, and the bottom end of the magnetic tile leaf spring is fixed with a guide plate shaft by bolts, and the guide plate shaft is hingedly installed in the spiral waist groove of the displacement turntable through an oil-free bushing.

[0013] An annular guide plate cover is fixedly provided on the rotating guide plate, and the guide plate cover is used to prevent the bottom of the magnetic tile leaf spring from falling out of the radial strip groove of the rotating guide plate.

[0014] A magnetic shoe support flange seat is also provided on the inner periphery of the guide plate cover.

[0046] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] like Figure 1 and Figure 2 As shown, the main structure of the device is the magnetic tile sticking mechanism B0 and the magnetic tile spreading mechanism C0; the target of this device is the rotor assembly A0, as shown in Figure 3 As shown, rotor assembly A0 includes magnetic tiles A2 and housing A1. The purpose is to radially extend magnetic tiles A2 outward and tighten them against the inner wall of housing A1. A magnetic tile expansion mechanism C0 is mounted on the side of magnetic tile attachment mechanism B0. Rotor assembly A0 is mounted on magnetic tile attachment mechanism B0. Magnetic tile expansion mechanism C0 drives magnetic tile attachment mechanism B0 to tighten the magnetic tiles within magnetic tile attachment mechanism B0.

[0048] like Figures 14-19 As shown, the magnetic tile attachment mechanism B0 includes a mounting base B1, a magnet B2, a magnetic tile attachment leaf spring B3, a rotating guide plate B7, a magnetic tile support hand B8, a turntable positioning pin B10, a displacement turntable B12 and a support hand coaxial mounting flange B14;

[0049] The support hand coaxial mounting flange B14 is fixed to the center of the mounting base B1. The annular rotating guide plate B7 is fixed to the mounting base B1 around the support hand coaxial mounting flange B14 via the turntable locating pins B10 and the support sleeve B15 on the surrounding edge. The rotating guide plate B7 is located around the support hand coaxial mounting flange B14. There is a gap between the rotating guide plate B7 and the support hand coaxial mounting flange B14, and there is no contact or connection. The magnetic shoe support hand B8 is fixed to the top surface of the support hand coaxial mounting flange B14. The outer peripheral surface of the magnetic shoe support hand B8 is provided with N grooves for installing the magnetic shoe leaf spring B3. Each groove is installed with a magnet B2, a magnetic shoe leaf spring B3 and a magnetic shoe A2 of the rotor assembly A0. The magnetic shoe A2 of the rotor assembly A0 is pre-installed in the groove and is attracted by the magnet B2.

[0050] The rotating guide plate B7 is provided with N radial strip grooves evenly spaced along the circumference, which are used for the magnetic tile leaf spring B3 to pass through and guide the movement as precision matching slots. The radial strip grooves are arranged radially. A rotatable displacement turntable B12 is provided between the rotating guide plate B7 and the mounting base B1. The displacement turntable B12 is provided with N spiral waist grooves evenly spaced along the circumference, which are used for the magnetic tile leaf spring B3 to pass through and guide the rotation as rotational motion slots. Figure 10 As shown, each spiral waist groove is an arcuate segment along a flat thread, and the N spiral waist grooves have the same spiral direction. A radial extension arm is fixed to one side of the displacement turntable B12. The radial extension arm extends from between the rotating guide plate B7 and the mounting base B1 and is hinged to the rotating head C3 of the magnetic shoe expansion mechanism C0.

[0051] The rotating guide plate B7 is positioned and installed on the mounting base B1 through the turntable positioning pin B10 around the edge. The turntable positioning pin B10 between the rotating guide plate B7 and the mounting base B1 is sheathed with a support shaft sleeve B15. The upper and lower ends of the support shaft sleeve B15 are respectively connected to the bottom surface of the rotating guide plate B7 and the top surface of the mounting base B1, and are used to support and install the rotating guide plate B7.

[0052] One magnetic tile leaf spring B3 is installed in a radial strip groove and a spiral waist groove, and a total of N magnetic tile leaf springs B3 are installed in N radial strip grooves and N spiral waist grooves.

[0053] In the groove position, the magnetic tile leaf spring B3 is arranged in the middle, and magnets B2 for magnetically attracting the magnetic tile A2 of the rotor assembly A0 are provided on both sides of the magnetic tile leaf spring B3.

[0054] like Figure 13 、 Figure 17 and Figure 18 As shown, the magnetic tile leaf spring B3 is L-shaped, one end of the L-shaped magnetic tile leaf spring B3 is horizontally arranged as the bottom end, and one end of the L-shaped magnetic tile leaf spring B3 is vertically arranged as the top end. The top end of the magnetic tile leaf spring B3 passes through the magnetic tile support flange seat B9 and can be horizontally movably embedded in the groove position of the magnetic tile support hand B8. The top end of the magnetic tile leaf spring B3 is provided with an elastic spring structure for contacting the magnetic tile A2 of the rotor assembly A0 on the radially outward side. The bottom end of the magnetic tile leaf spring B3 can be horizontally movably embedded in the radial strip groove of the rotating guide plate B7, and the bottom end of the magnetic tile leaf spring B3 is fixed with a guide plate shaft B4 by bolts. The guide plate shaft B4 is hingedly installed in the spiral waist groove of the displacement turntable B12 through an oil-free bushing B5, and is driven to move by the displacement turntable B12.

[0055] like Figure 14 and Figure 6As shown, an annular guide plate cover B6 is fixed on the rotating guide plate B7. The guide plate cover B6 is used to prevent the bottom of the magnetic tile leaf spring B3 from falling out of the radial strip groove of the rotating guide plate B7.

[0056] The inner circumference of the guide plate cover B6 is also provided with a magnetic shoe support flange seat B9. Like the rotating guide plate B7, the magnetic shoe support flange seat B9 is provided with N radial strip grooves evenly spaced in the circumference for the magnetic shoe leaf spring B3 to pass through and guide the movement. Figure 11 As shown, the outer edge of the upper end surface of the magnetic shoe support flange B9 is provided with an annular step for positioning the housing A1 of the rotor assembly A0. The housing A1 of the rotor assembly A0 is mounted on the annular step of the magnetic shoe support flange B9. The magnetic shoe support flange B9 does not actually contact the magnetic shoe support B8.

[0057] The magnetic shoe support arm B8 is non-rotatably mounted on the top surface of the support arm's coaxial mounting flange B14 via a first housing locating pin B16. The rotor assembly A0's housing A1 is non-rotatably mounted on the magnetic shoe support arm B8 via a second housing locating pin B17. After the rotor assembly A0's housing A1 is fitted over the annular step of the magnetic shoe support arm's flange seat B9, the second housing locating pin B17 is inserted through the pinholes in the housing A1 and the magnetic shoe support arm B8, maintaining the circumferential position of the housing A1.

[0058] The mounting base B1 is also provided with handles B13 on both sides for easy lifting.

[0059] The mounting base B1 is also provided with a positioning sleeve B11 for mounting on external equipment.

[0060] like Figure 4 As shown, the magnetic tile opening mechanism C0 includes a cylinder C2, a rotating head C3, a limit seat C5 and a limit bolt C6. The cylinder C2 is fixedly installed through the cylinder fixing seat C1, and the cylinder rod of the cylinder C2 is connected to the magnetic tile sticking mechanism B0 through the rotating head C3; a limit seat C5 and a limit bolt C6 for limiting the movement of the rotating head C3 are also provided in front of the rotating head C3. The limit seat C5 is fixedly installed, and the limit bolt C6 is installed on the limit seat C5 through threads. The limit bolt C6 and the cylinder rod of the cylinder C2 are in the same straight line and are used to support the extreme position movement of the rotating head C3.

[0061] A pin hole is provided on the radial extension arm and the rotating head C3 of the displacement turntable B12 of the magnetic tile mechanism B0. Pins C4 are inserted into the pin holes on the radial extension arm and the rotating head C3, so that the radial extension arm and the rotating head C3 of the displacement turntable B12 are hinged.

[0062] like Figure 1As shown, the specific implementation includes: the hand support coaxial mounting flange B14 is fixed on B1 according to the center positioning cylindrical feature, the displacement turntable B12 is inserted into the maximum outer circle of the hand support coaxial mounting flange B14, and the displacement turntable B12 and the hand support coaxial mounting flange B14 are rotatably connected and can rotate around the hand support coaxial mounting flange B14.

[0063] The oil-free bushing B5 is placed in the rotation groove of the displacement turntable B12. The oil-free bushing B5 is made of brass, which can reduce friction and has low hardness and good lubricity. The oil-free bushing B5 is inserted into the guide plate shaft B4, which is fixed to the magnetic tile leaf spring B3. The rotating guide plate B7 is fixed to the support shaft sleeve B15 according to the slot position. Figure 16 As shown, the height of the support sleeve B15 is 0.02mm to 0.04mm greater than the thickness of the displacement turntable B12. This ensures that although the displacement turntable B12 is between the rotating guide plate B7 and the mounting base B1, it will not be pressed by the rotating guide plate B7 and cannot rotate, and can press the displacement turntable B12 so that it will not move in the Z direction.

[0064] like Figure 9 As shown, the slot width of the rotating guide plate B7 is precisely aligned with the width of the tile spring B3, with a clearance of 0.02mm to 0.05mm. This constrains the tile spring B3 within the slot of the rotating guide plate B7, restricting its linear motion to zero. The guide plate cover B6 is fixed to the rotating guide plate B7, holding the tile spring B3 in place during movement, preventing it from shifting or deflecting.

[0065] Cylinder C2 is fixed to cylinder mount C1 via its rear shaft. This shaft allows cylinder C2 to rotate about the shaft, preventing radial forces from causing cylinder C2 to become stuck during movement. A pin C4 connects rotating head C3 and displacement disc B12, allowing them to rotate relative to each other, converting the linear motion of rotating head C3 into the rotational motion of displacement disc B12.

[0066] The magnetic tile leaf spring B3 is made of 65Mn material, and its unique spring structure is calculated by the pressure required for the fit between the magnetic tile A2 and the shell A1. The structure is as follows: Figure 13 This ensures that the magnetic tile A2 and the shell A1 are subjected to the expected pressure value during the bonding process and that the rigid structure of the magnetic tile A2 and the shell A1 will not be damaged due to excessive pressure.

[0067] The specific operation process of the present invention is as follows:

[0068] like Figure 7As shown, eight magnetic tiles A2 are pre-placed in the grooves of the magnetic tile support B8. A magnet B2 is installed on both sides of each groove of the magnetic tile support B8. The magnet B2 provides magnetic attraction to the magnetic tile A2 to prevent A2 from tipping over.

[0069] like Figure 8 As shown, the housing A1 is positioned on the magnetic tile mechanism B0 by the first housing positioning pin B16 and the second housing positioning pin B17;

[0070] like Figure 11 As shown, the Z-direction height difference between the magnetic shoe A2 and the shell A1 is ensured by the step of the magnetic shoe support flange seat B9. The shell A1 is located on the outer step of the magnetic shoe support flange seat B9, and the magnetic shoe A2 is located on the inner step of the magnetic shoe support flange seat B9. The height difference between the inner and outer steps of the magnetic shoe support flange seat B9 is the Z-direction distance value between the magnetic shoe A2 and the shell A1.

[0071] After assembly Figure 5 shown.

[0072] like Figure 12 As shown, after the magnetic tile A2 and the shell A1 are placed, the cylinder C2 extends to push the rotating head C3 forward, thereby driving the displacement turntable B12 to rotate around the coaxial mounting flange B14 of the support arm, and the relationship between the rotational motion slot of the displacement turntable B12 and the guide plate rotating shaft B4 drives the guide plate rotating shaft B4 to move, and then drives the magnetic tile leaf spring B3 to move. Since the magnetic tile leaf spring B3 is limited by the precise matching slot of the rotating guide plate B7, the rotational motion is converted into the linear motion of the magnetic tile leaf spring B3, and then the magnetic tile leaf spring B3 can move radially outward or inward, and the linear motion of the magnetic tile leaf spring B3 is also guaranteed by the precise matching slot of the rotating guide plate B7.

[0073] If the extension / retraction direction of the cylinder C2 and the spiral direction of the rotational motion slot of the displacement turntable B12 are adjusted and set, the magnetic tile leaf spring B3 can be driven to push the magnetic tile A2 outward so that the magnetic tile A2 is tightly attached to the inner wall of the shell A1.

[0074] After the bonding is completed, the cylinder C2 retracts and resets the magnetic tile leaf spring B3 along the above-mentioned motion transmission path; finally, the rotor assembly A0 flows out of the device to end this cycle and start the next cycle.
